PRIMIN'G DEVICE FOR INTERNAL-COMBUSTION ENGINES.

Specification of Letters Patent. Patented 00 13. 21, .1919.

Application filed November 26, 1917. Serial No. 203,875.

To all whom it may concern:

Be it known that I,VJOSEPH H. LYONS', a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Priming Devices for Inter'naLCombustion Engines, of which the following is a full, clear, and exact description.

In many cases it is desirable, and frequently it is necessary, to discharge into the cylinders or the inlet manifold of an internal combustion engine, a quantity of easily vaporized liquid fuel before the engine can be started. In some cases gasolene may be used for this purpose, but generally speaking, it is desirable to use some fluid fuel which vaporizes more readily than gasolene, as for example,'alcohol or, preferably, ether.

The present invention is a device adapted to be easily attached to the cylinders or inlet manifold of an internalcombustion engine, and with which one may easily and without loss "discharge into each cylinder or into the manifold a definite quantity of this easily vaporizable fuel.

. The invention consists in the construction and combination of parts shown in the drawingand hereinafter described and pointed out definitely in the appended claims.

In the drawing, Figure 1 is an end View of the .device; Fig. 2 is a side elevation with the body portion sectioned and the valvepartly sectioned; Figs. 3, 4, 5 and 6 are vertical transverse sections through the device showing the valve thereof in various positions; Fig. 7 is a side elevation of the device; Fig.8 is an'end view of the small end of the valve; Fig. 9 is an inside view of the washer, 30. Fig. 10 is an end view of nut 35.

Referring to the parts by reference char acters, 10 represents the tubular body of the device, which has its lower end 12 threaded to facilitate its connection with an engine cylinder or manifold. This body is likewise formed at its upperend with a cup 13 for receiving the fuel to be discharged, by means of the device, into said cylinder or manifold.

1 Midway between the endsof this body is a transverse barrel 14, which is internally tapered, The hole 15 he pp r p rt of the body and the discharge hole 16 in the lower part of the body connect with the conical bore of this barrel.

20 represents a hollow conicalvalve which is rotatably fitted within the barrel'l4; and it has on its large end an operating handle 21; and is formed 'on its small end with an axially disposed stem 22, the end 23 of which is threaded. This stem is flattened as shown tofit a hole in the washer 30.

This washer, 3O fits against the small end of the barrel and closes it. It isv formed with a central sleeve 31, atthe inner end of which is an inturned flange 32.- The hole within the flange 32 is of such shape that it loosely fits around the flattened stem 22,-.so that when'the valve is turned the washer must also'turn. A coil spring34 is placed within the sleeve 31 in engagementwith the flange 32; and a cap nut 35 is screwed onto the end of the stem against this spring thereby putting it under tension, with the result that the washer 30 will be held firmly against the end of the barrel '14, and the valve 20 will be drawn snu-glyinto the conical hole through this barrel, but if the valve should chance to stick in'the barrel it might still be drawn endwise to loosen, because the spring 34 will yieldsufficiently for this purpose, and the diameter of the nut is such that it may telescope into the washer sleeve 31.

As stated, the valve 20 is hollow, but it has in its walls numerous holes, the location and purpose of which will now be explained. There are first two filling holes 24, 25, which are of such size and so located thatwhen the valve is in the position shown inFigs. 2 and 3, both of these holes will be in communication with the filling hole 15 in the upper part of the body. When the valve is in this position there is no hole through its opposite wall communicating with the discharge hole- 16. Through the wall of the valve there is however, a discharge hole 26; and the valve may be turned to the emptying position shown in Fig. 6, whereby the interior of the valve is placed in communication with the discharge hole 16. There Fig. 5 any fluid poured into the cup will pass immediately through the valve to the discharge hole 16.

These various holes are so placed that the valve may be turned to the position as shown in Fig. 4, in which fluid can neither run into or out of the hollow valve.

011 the large end of the barrel is a graduation mark 40; and on the large end of the valve are other graduation marks F and E for cooperation with it, so that the operator may know when he has turned the valve to bring it into the desired position. In the small end of the barrel are several V-shaped notches 29; and on the inner face of the washer is a V-shaped lug 39 for engagement with one or the other of said notches. When the operator turns the valve he necessarily turns this washer, and he knows when he has turned the valve to the proper position, by the graduation marks adjacent the handle, and when he has reached the proper position this lug will snap into one of said notches, and hold the valve against accidental displacement.

When the valve is in the position shown in Figs. 2 and 3, and ether or other volatile fuel liquid is put in the cup, it will flow into the hollow valve, through one or the other of the holes 24, 25,-while the displaced air will flow out through the other hole. Generally the valve will be put into the position shown in Fig. 4, and the cup filled. Then the valve will be quickly turned to the position shown in Fig. 3. If there be only one of the holes 24, 25, there will be such delay in the flowing of the fuel into the valve, and such a stirring up of said fluid by the escaping air, that a substantial loss of fuel by volatilization will take place before the fuel flows into the valve.

When the fuel is in the valve, it may be carried therein as long as desired, if the valve is in the position shown in Fig. 4. When the valve is turned to the position shown in Fig. 6, this fuel will flow out of the valve and through the hole 16, to the engine.

The end of the nut 35 is formed with a series of ratchet like teeth 35 on its inner end. The end 39 of the coil spring 34 is turned up so as to engage these teeth. Therefore the spring, while it will permit the nut to be screwed onto the stem, will act as a lock to prevent said nut from being unscrewed.

Having described my invention, I claim 1. In a device of the character specified, the combination of a tubular body having a transversely disposed internally conical barrel which intersects the hole through the body, a conical valve which is rotatably fi ted in said barrel and has a stem which projects from its small end out of said barrel, a washer which embraces said stem and may slide upon it but must turn with it and which engages against the small end of the barrel, said engaging surfaces having the one a V-shaped projection and the other a plurality of notches to which said projection is fitted, a nut which screws onto the end of said stem, and a spring which surrounds said stem and is composed between said collar and nut.
